it looks like the front axle bushing from the outer half of the CAD of a 4wd.
or maybe the race out of a front wheel bearing.

it would be sort of evil fun to take a bunch of odd ball parts and toss them randomly under people's trucks.

 

**** ring

 

Here is a better picture of the sides.

 

it looks like an inner bearing race to me.... how big is it anyways? We got people sayin everything from a wedding ring to wheel bearing lol....

 

It is about the size of a wedding ring. Does it look like it would come off one of our trucks?

 

It was most likey of the f150 parked next to you at the time. lol Ya it sure looks like bearing race. But its still in one peace for the most part.

 

If it the size of a wedding ring, my first thought would be it is part of one of those rings that has a spinning band on it. If this is the case, it could have fallen off of someone's hand and broken, and you just happened to find the larger of the two parts that fits against the finger. The rest of it could be laying around the area you found this piece.

 

RON333 I really like that paint job man looks good.
